Kinesin heavy chain is essential for viability and neuromuscular functions in Drosophila, but mutants show no defects in mitosis

Abstract

The in vivo function of the microtubule motor protein kinesin was examined in Drosophila using genetics and immunolocalization. Kinesin heavy chain mutations (khc) cause abnormal behavior and lethality. Mutant larvae exhibit loss of mobility and tactile responsiveness in the most posterior segments, followed by general paralysis and death during larval or pupal development. Adults homozygous for a temperature-sensitive allele also exhibit a loss in mobility and sensory responses. The data indicate that kinesin function is essential and suggest that kinesin has an important role in the neuromuscular system, perhaps as a motor for axonal transport. The possibility of more general cellular functions remains open, but observation of embryogenesis and morphogenesis in khc mutants suggests that mitosis and the cell cycle can proceed in spite of impaired kinesin function. Immunolocalization suggests that kinesin may have some general cellular functions but that it is not a major component of mitotic spindles.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
